TIN-OPENER.

Specification of Letters Patent.

Patented July so, 1912.

Application filed September 12, 1910. Serial No. 581,642.

To all whom it may concern:

Be it known that I, BOHUMIL J IROTKA, a subject of the Emperor of Austria-Hungary, residing at Berlin, in the Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in Tin Openers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to a tin with a tin-opener attached thereto.

With many kinds of tins, particularly such containing shoe-cream, it is a great inconvenience, that they are not easily opened, as they must close tightly and hermetically in order to prevent the contents drying up.

The object of the present invention is to remedy this difiiculty by means of a simple device attached to the tin, by means of which the lid may be raised without any exertion.

In the accompanying drawing the invention is exemplified in various constructional forms.

Figure 1 is a side view of the tin; Fig. 2 is a plan view of the lower part of a tin with opener; Figs. 3 and i show another modification of the tin; Fig. 5 is a third modification; Fig. 6 is a fourth modification.

The tin consists of the lid a and the bottom 6. The lid a is provided with a flange 0. To any suitable part of the bottom I) is attached the opener, which is substantially made of a piece of wire, the one end of which is curved at e and has a pivoting pin f. The pin f is inserted into a hole in the bottom 6 and spread into a head 9, Fig. 2, on the inner side. On the lever 03, Fig. 1, being moved into the position shown by dotted lines, the curved part e will press against the flange 0 of the lid a and lift the latter, so that the tin is opened. In place of wire the opener may also be made of a piece of strong sheet metal. It is however not necessary to provide a flange on the lid. The arrangement may also be made in such a manner that the opener is sunk into the one side of the bottom, and the curved part 0 bears against the sharp edge of the lid. This is the case with the modification shown in Figs. 3 and 4 where the lever 72, lifts the lid by means of a projection 2', said projection z' moving in a recess 7a in the bottom. Another, third modification consists in the lid a being provided with a notch Z and the lever h acting against the curve m of said notch Z, so that the lid is turned a piece while it is being lifted.

Fig. 6 shows another modification in which the small finger-plate n has been sunk in the-tin, so as to allow of more conveniently packing the same.

The hereinbefore described device allows of a convenient and easy opening of the tin and as the opener is secured to the tin, it can never get lost.

I claim:

A tin combined with an opener consisting of a double armed lever, a bottom part with an indent, a lid with a notch with an inclined side, said lever pivotally arranged on the bottom part, the one arm of said lever having a projection moving in the indent of the bot-tom part and acting in a notch in the rim of the lid against the inclined side of said notch.

In testimony whereof I affix my signature in presence of two witnesses.
